sun, I didn't spray anything on them and this morning the leaves were all green and then tonight they have brown spots and some holes. If were bacteria or virus I wouldn't think it would happen this fast in twelve hours... Any explanations would be appreciated!

Yes, the newer growth can be sunburned with bright sunny days like today with high UV

Yep. Leaf burns are still possible at the end of the vines. I got some today on the end of my main and secondary vines. It was 90F here, and not a cloud in the sky. High UV like Wilbur noted. Forgot to shade some of the new leaves and some got burnt. Try to keep the pumpkin shaded too. They can get real hot inside on days like these, and sometimes just shut down or start to rot from the inside out.

Not new growth though they were mature leaves in the middle of the plant!
